IQ and Brain Volume Use all of the paired IQ scores and brain volumes in Data Set 9

“IQ and Brain Size” in Appendix B. Appendix B Data Sets. In Exercises 25–32, use the data in Appendix B to construct a scatterplot, find the value of the linear correlation coefficient r, and find either the P-value or the critical values of r using A  0.05. Determine whether there is sufficient evidence to support the claim of a linear correlation between the two variables. (Save your work because the same data sets will be used in Section 10-2 exercises.)
